1st Fully Built 5.5Gen - NA
I just called TurboXS about the connection problem and they told me that it is a known issue and there is no fix from them in the works. Rebooting the tuner after the fact is the known fix. Other than that, we're all left to come up with fixes on our own. Awesome.

Could throw it on a switch like Darren said, but what a PITA.

The Tuner has to see the UTEC ON and booted up as soon as it turns on for them to interface. If I want my tuner and utec to interface, what I do is turn the ignition switch all the way to on and wait for the auto climate control display to come up, then quickly turn it off (the utec holds power for a few seconds) and back on. That causes the tuner to recognize the UTEC and it's all good to go. A switch would work as well, but I just flick my key twice... not a big deal.

I need to clarify this so that I understand you. We were taking before about that one issue you were trying to solve with your patch harness where you had startup issues because you or someone was saying the UTEC was cold or something. I don't recall those details at the moment. Something that you or John was suggesting was putting a heating pad on the UTEC or something like that. Was that not a Tuner related issue?
It actually took me quite a while to figure out that it was the UTEC case being cold that was causing the problem, but once I did it's not such a big deal anymore, just annoying/embarrassing until it warms up.

The interface sucks and takes a while to get used to, but it's a great tool and very easy once you're used to it. The misfire and tuner/UTEC linking problem can be annoying, but it's kinda a "oh well" for me at this point.
So yes, I hate it... but I couldn't think of a better option without trying to have my ECU modified (extra memory) for osiris or pay big money on one of the haltechs.

The UTEC must be wired in post ECU, and the Osirus uses the Consult interface, so, there is no pre/post ECU wiring needed, but a Z33 (post year A33B ECU) is required for it to work, unless you use a Z33 ECU .. Did I get that right? 
Jeff will be glad to hear about this, and I might put my first born up for sale....

I don't have to wait more than two seconds once the ignition is on. I flip it back off and on quickly and the tuner will reboot. It makes it work, but for something that costs as much as these things do, we shouldn't have to do things to 'make' them work.
One fix I am considering is to wire the UTEC to the accessory switch so that it gets to boot first. That can help to solve this problem but it's not the best solution I can come up with.

They have maps for them all. I don't think anyone has tried it on the max but I am pretty sure it will work.

It won't work on any of the early VQ ECUs that have a square connector, according to the Osiris guy that I was talking to on the Z forums. I believe some of the early G's were among this group.
Apparently the earlier ECUs do not have enough memory.
They said it may be possible to modify the ECU and add more memory, but I got the impression they would charge an exorbitant price.
Again just to clarify, they told me Osiris WILL NOT work on a 02-03 maxima ECU without modification.

Figured it would be able to at least do the 1map over and over. I know the others store 5 maps but that is pretty useless(very few people will use more than 3)
If you guys keep talking about this you'll make Paramy want to swap out his ECU with a newer one so we can use the Osiris on it. (I know that's what I would do). That whole package would still be cheaper than a Haltech.

The actual maps are probably a very minimal amount of storage. Just a small text file worth of info. It's probably the actual osiris program that needs the extra storage.
SOB! This is one less thing that I wanted to consider that I'm now considering. Damn you All Motor peeps!
I was actually waiting for a Haltech to come along, which I know would do more then I would need.
What are the pros and cons of the vs between going the Haltech route or the new ECU and Osiris route? I'm not positive that you can change cam timing on the Osiris program, and am I able to go in there an manipulate any single parameter I choose like so with the Utec or Haltech?
Also means that I can't run this Tuner wideband on it does it?
hmmmmmm......6th or 7th gen ECU should work right, or just 6th gen only cause of the 6-speed and HSLD?

You can use a z/g/6thgen/alt ecu. They all have the same connector I think

no the wires dont match up. the max ecu controls more things than the z ecu does. specificity gauges, AC, and fans, cc too.
and no the dealer cant program the key, the NATS system is totally different, it goes through the BCM on the z ecu.
this is so funny to come up now.... if u only knew what was sitting my car right now... hahahah
This has come up many times before, and i was encouraging the A34 to get it, but no one sacked up from what I remember.
I was never able to convince rich@uprev to even consider the 02-03 A33B, but it seems as if sparks sparked his interest more than I did. Although I was trying like 4 years ago or some shat.
So, to get this straight, as in nothing's changed, just the nomenclature of the subject.
Early G's and Maximas have the same ECU pinout/connector, so no go on either of those, as we've known (or at least thought we did) for at leat a few years now.
No WB's = a non issue Z33's, but will not work with G/A33B ECU's.
So, this just semi clarifies this .. sorta.

Good point! I would like to get as much working/functioning as possible with as little codes I'd have to disengage as I can though. Since this is a daily driver, and I would like to try and everything to function as it should. But yes that is an option.

This is what richard told me when we were gonna do it on my buddies maxima:
See if one of the local dealers are willing you help you. We never got around to it since my buddy went ahead and got a VAFC2

K,
Our product works with all of the 2002 and newer Nissan ECUs. We just don't directly support many of the vehicles as we don't have the ROM files to patch, nor have we done any base tunes to start with. If you're located near one of our Pro Tuners, they can download the ROM file from the ECU and submit it to us so that we can patch it for our tuning software. Once that is done then they can do the tuning at their facility. Understand that the Pro Tuners will charge for this tuning time, and it is not something that we control, our pricing is for our product only.
As we have more Maxima owners come forward and want their cars supported, the more ROM files we'll have available and the more base tunes we'll have available to support them. At this time we don't actually have a single Maxima ROM or base tune.
Where are you located?
